I had this chair for 5 Months now. It now makes creaks, I have to re tighten the screws once every two weeks now, and it collects dust in the lumbar area like crazy so now im dusting between the grooves now every one- two weeks as well. While the chair is still comfortable to sit in I just never had to do so much with previous chairs. By the way I weight 255  sit in the chair like a couch as im always at my desk. Hope this helps
